BRICK-KILN.

Specification of Letters Patent No. 8,678, dated January 20, 1852.

Y To all whom z' may concern things before known, and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawing, in which- Figure l, is a sectional view. Fig. 2, is a general view of the kiln with a portion of the walls removed to show the fire bed, etc.

My improvements consist in the formv of the bottom of the fire arches, and in the mode of introducing the air into the furnace for ignit-ing and burning the fuel and causing a free, steady, and unimpeded heat, equalized throughout the body of the kiln, by which I am enabled to greatly economize the fuel, and burn a kiln of bricks, or other articles manufactured of clay, more evenly and expeditiously than by any other mode with which I am acquainted.

The construction is as follows: An arch (a) is formed a little below and between each of the fire beds (Z2) in which lateral openings (c) are made that serve to admit the air up into the re bed (b) through the conductors or interstices (d) made therein, so as to cause a free current of air to every portion of the re bed, for` the purpose of equally igniting the fuel thereon, as before stated. their bottom, as at A, Fig. l, or straight, as at B; but the former is preferable, as in that case the ashes are discharged intothe airchamber, and the fire kept free. The bottom of the fire-bed may be covered with an iron grate, as at (e), and this is essential The interstices may be inclined at where coal is the fuel used. The other portions of the kiln are built in the usual way, or they can be made according to any of the modes employed.

It is obvious from the above description that a blast from a fan, or other mechanican means, can be employed to facilitate the operation of the furnace, economize the consumption of fuel,`and shorten the time required for properly burning the kiln.

Having thus fully described my improvements, what I claim therein as new, and for which I desire to secure Letters Patent, is-

Forming air arches or openings in the kiln between the fire beds with lateral openings therein through `which a sufficient amount of air can be supplied equably to all parts of the fire-bed at the same time, substantially as herein described.
